Back in July 2019 I created this small setup to power my 12v Ham radio station. At the time I had one radio which consumed 1amp on standby and like 7 or 8 at full power (100w) transmission. I was using the radio a few nights a week for about 4-5 hours and only transmitting occasionally not all the time. About December 2021 I added another radio that consumed 2amp on standby so I added a second battery in parallel. I never had any issues with anything and never had to use my plug-in 12v power supply.
The setup consists of:
One Mission Solar 375w panel laying on my flat roof
Morning Star 25a MPPT controller model PS-MPPT-25M
2 x Trojan 27TMX 12V 105AH flooded lead acid battery in parallel
Various breakers, buss bars, cables
I bought all my stuff locally. I didn't take a picture of the solar panel in my wife's Prius with me scrunched down could barely drive it looked so funny! The breakers and buss bars were purchased at a local marine store. They actually had a lot of stuff to do solar on your boat. A lot of "blue" stuff (Victron). The Morning Star and stuff for PV wires was purchased at a local solar supply store.
Anyways, I'm not doing Ham radio anymore so I'm going to sell this setup and I want to build a small off-grid setup to power some appliances using extension cords.

Here is my solar panel. The roof is flat on one side then it goes up and there are these tiles. So I laid the panel on the tiles, facing south, I think it a very good angle.
Charge controller. One the right is a breaker for the positive side of the PV panel. On the left is the output from the CC that goes to the battery and with another breaker.
Two batteries in parallel. Output from the batteries to another breaker then to the buss bar where I distribute the power. One of those pairs of wires goes to a 12v fused power block (West Mountain Radio "RigRunner") which distributes to two ham radios and other 12v equipment.
I bought this "remote meter" so I could have it in my radio shack. The rest of the equipment is under a portion of the house.
